'CABLE-T'RAMWAY GRIP.

SPECIFICATION forming part of Letters Patent No. 650,590, dated Mayv29, 1900. 7

Application filed October 18, 1899. Serial No. 733,762. (No model.

To all whom it may concern:

Be it known that I, ALFRED RossNHoLz, a citizen of the United States, residing in the city and county of San Francisco, State of Californiu, have invented an Improvement in Cabie-Tramway Grips; and I hereby declare .the following to be a full, clear, and exact deto me" April 11, 1893; and itc'onsi'sts in a.

means for mounting the gripping-jaws so that they are turnable and automatically adjustable to the line of travel of the cable upon which they are closed. Thus when the cables are running ata considerable incline up or down the weight being suspended vertically by gravitation will hang at a considerable angle with the line of the cable, and in order to make the grip effective and avoid kinks in the cable its automatic adj ustment allows it to turn so as to follow'the direction of the cable without reference to the position of the hanger and load.

My invention also comprises details of com structionwhich will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is an end elevation of the apparatus. Fig. 2 is aside elevation, showing the apparatus at a release-station where the jaws are-to be unclasped from the rope. Fig. 3 is an enlarged section transverse to the line of the rope. Fig. 4 is a front view of the same. Fig, 5 is 'a plan view. Fig. 6 is a modification showing a compound lever to actuate the grip.

A isa yoke or frame of any suitable description, from which the load or bucket B is to be suspended. Through the upper part of the frame of the yoke A pass the rods (1, which are slidablo approximate] y vertically through this yoke, and to the upper ends of these rods is swiveled a frame 1), which carries the rollers E. These rollers are adapted to travel C are connected eitherdirectly or indirectly with a movable jaw Fof the grip, this jaw being fulcrumed at f and havinga lever-arm G extending approximately horizontally from it, so as to be actuated by the rods 0. The connection between the jaw F and the rod 0 may either be direct, as shown in Figs. 1 to 5, or its lever-arm G may have its outer end acted upon by a supplementary fulcrumed lever'G, as shown in Fig. 6, so as to produce a compound lever action to act upon the grip l with increased force, the rods 0 pulling upon the lever G and the power from this lever being transmitted to the lever G and thence to the jaw F.

F is a jaw which is stationary with relatio to the fulcrumed and movable jaw so far as the opening and closing of the jaws are concerned; but this jaw is mounted uponor forms a part of a cylindrical sleeve II, which is turnable upon its horizontal axis in boxes I up n the main frame A. This rovoluble sleeve is slotted vertically through the centor, as shown at h, the slot being of suflicient length to allow ample movement of the leverarm G, which actuates the grip.

The lower ends of the rod 0 are connected with the lever-arm G by means of a swivel-box J, which fits and is turnablo upon the outer end of the lever G, this end being made cylindrical for that purpose. The box J has arms K extending outwardly from it, and to these arms the lower ends of the rods 0 are connected, as plainly shown in Figs. 3, 5, and

By this construction, the weight suspended from the frame or yoke A being borne by tho pulleys E, the slidable rods 0, which are connected with the pulley-frame D, will allow the frame A to sink by reason of theweight, and this movement of the frame and the lower fixed jaw F acts upon the movable jaw F through its lcver-arms G or G to close the jaw upon the traveling rope or cable 1. At the same time by reason of the turnable or swivel head whichcarries the lower jaw,

the two jaws are allowed to turn about the axial line of this swivel part, so that when the direction of the cable changes either up or down with relation to the hanger the change of angle of the traveling cable willbe followed by the grips, which will thus always take a line of the cable and remain parallel with it whatever its changes of angle. The distance to which the grips can turn or swivel in either direction may be determined by i stops W. When the load arrives at a releasestation, the supporting-pulleys E run upon the rigid supporting-track O. Beneath this lowing it to continue runningwhile the load stops;

Having thus described my invention, what I-claim as new, and desire to secure by Letters Patent, isa 1. In acable-tramway conveyer,thetrolleyframe movably carried thereon adaptedto travel upon the cable, apairof jaws adapted to engage with the movable cable, one of said jaws being movable, and mechanism connecting the trolley-frame with the movable jaw whereby motion is communicated to said jaw,

a stationary jaw opposed thereto between which and the movable jaw the cable is gripped, and a swiveLsupport' for said jaws.

2. In a cable-tramway conveyer,a load'supporting frame, amovable trolley-frame, jaws adaptedto gripa travglingcable, one of said jaws being movable and having connection between it and the trolley wherebyit is closed upon the fixed jaw by the action of the weight,

' anda support for the gripping-jaws turnable in the load-carrying frame, whereby the jaws automatically ad just themselves to the line of the c'able'.

3. Ida cable-tramway conveyer, a load-supporting f rame,a trolley adapted to travel upon a stationary cable, rods connected therewith sliclable through the supportingframe, a swivel-box with which the lower ends of said rodsanecnnnected afulcrumed gripping-jaw having a lever-arm, upon the outer end of which the swivel-box is turnable, and a sec- .ond jaw-between whichand the movable jaw, the traveling cable is gripped, said jaws bQ'r, ing turnably connected with the load-sui pending frame.

4. In a cable-tramway conveyor, trolfha" mounted in-a frame and adapted to trans upon a stationarycable, rods connected with the trolley-frame extending downwardly, a load suspending frame vertically slidable with relation to said rods, a grippingjaw mounted and turnable within the load-suspending frame and having a vertical central slot through its turnable head, a second jaw fulcrumed so as to open and close with relation to the first-named jaw having a leverarm extending through the slot in the turnable head of the first jaw and swivel connections between the vertical rods and said lever-arm.

5. In a cable-tramway conveyor, the com bination of the conveyor-frame and a trolleyframe movably carried thereon and adapted to travel upon a track or cable, a pair of jaws adapted to engage with the moving cable and rotatively mounted to automaticailyadjust themselves to the line of the cable, one of said jaws being movable with relation to the other, a mechanism connecting the trolley-frame with the movable jaw whereby the latter is closed to grip the cable between it and the stationary jaw by the suspended weight, a supplemental track disposed with relation to the main track orcable,and a pulleycarried by the conveyor-frame adapted to ride upon said track tosupport the main frame so that the gripping-jaws are released from the traveling cable.

6. In combination with a tramway-carriage frame, rods movably suspended therefrom, their lower ends suitably connected with an arm extending through a slotted cylindrical head, the front part of said arm and cylindrical head terminating as gripping-jaws, both being turnable as a wholeon their horizontal axis transverse to therope in channeled boxes orbearings bolted to the suspendingframe, a'cable adapted to rest on the lower jaw, and gripped to the latter by the oppositely-movable jaw which terminates the horizontal arm or lever, and a semi-universal joint connecting said lever with the carriageframe.

In witness whereof I havehereunto set my hand.

ALFRED ROSENHOILZ.
